Explanation & Answer
The function f(x) equals the set of ordered pairs: { (0,0) , (1,2) , (2,3) , (3,4) } These ordered pairs are in the format (x,y)....so if you are finding f(x), then your answer, in this case, would be the y-coordinate that x belongs to (ie. for ordered pair (1,2) f(1) = 2.
So for this one you need to find f(2). When x=2 in the set above, then y=3 (You can see this by looking at the ordered pair (2,3)). So f(2)=3.

If 1 of the 200 test subjects is randomly selected, find the probability that the subject had a positive test result, given that the subject actually uses drugs. That is,
find (positive test result ? subject uses drugs).

3. This is observation from previous years about the impact of students working while they are enrolled in classes, due to students too much work, they are spending less time on their classes. First, the observer need to find out, on average, how many hours a week students are working. They know from previous studies that the standard deviation of this variable is about 5 hours. A survey of 200 students provides a sample mean of 7.10 hours worked. What is a 95% confidence interval based on this sample?

Exchange Paradox, statistics homework help
Rest of the problems are in the attached file. I also attached book.1.(the Exchange Paradox) You’re playing the following game against an opponent,
with a referee also taking part. The referee has two envelopes (numbered 1 and 2 for the sake of
this problem, but when the game is played the envelopes have no markings on them), and (without
you or your opponent seeing what she does) she puts $m in envelope 1 and $2 m in envelope 2 for
some m > 0 (treat m as continuous in this problem even though in practice it would have to be
rounded to the nearest dollar or penny). You and your opponent each get one of the envelopes
at random. You open your envelope secretly and find $x (your opponent also looks secretly in his
envelope), and the referee then asks you if you want to trade envelopes with your opponent. You
reason that if you trade, you will get either $ x
2 or $2 x, each with probability 1
2 . This makes the
expected value of the amount of money you’ll get if you trade equal to
1
2
$x
2
+
1
2
($2 x) = $5x
4 ,
which is greater than the $x you currently have, so you o↵er to trade. The paradox is that your
opponent is capable of making exactly the same calculation. How can the trade be advantageous
for both of you?
